Grammar Design
Shape syntax around the real moves experts make in the domain.
Language Creation
Make a language when ordinary commands are too blunt.
Hammer is a workspace for creating domain-specific languages, grammars, and command systems.
Designed For
Toolmakers who need precise expression for repeated expert workflows.
Hammer turns recurring patterns into syntax, parsers, and engines that make the work faster and less ambiguous.
Engine Hooks
Connect parsed language to actions, transforms, or generation.
Iteration Harness
Test examples until the language feels small, expressive, and hard to misuse.
Practice Loop
- Collect repeated commands and examples.
- Design the grammar and execution model.
- Test the language against real work.
